Problem Statement-1 Magnify a triangle placed at A (0,0), B (1,1) and C (5,2) to twice its size keeping the point C (5,2) Fixed. If the point C (5,2) needs to be fixed this means the transformation scaling needs to be done with respect to the point C (5,2). So, we will bring the point […]
Example – 2 (from Exams) Rotate a triangle placed at A(0,0), B(1,1) and C(5,2) by an angle 45 with respect to point P(-1,-1). The calculations available for computer graphics can be performed only at origin. It is a case of composite transformation which means this can be performed when more than one transformation is performed. […]
In simple words , scaling means an object can be viewed differently with various scales. An object with length 3cm might appear small when viewed with a scale in meters. Cars will appear bigger if you are looking down on the cars parked at a parking lot from 2nd floor of a building, but same […]
Welcome again to learn a complex topic simply. Learn by solving numerical problems. Let the theory take a back seat this time. Moving, Rotating , Zoom-in or Zoom out an object on the screen is called Transformations. There are two types of transformations in computer graphics. Geometric Transformations Coordinate Transformations Geometric Transformations – As the […]
Problem Statement: An object is placed with respect to origin on (2,1). Now move the object away from the origin by 2 steps in x and 3 steps in y. What would be new coordinates to the moved object. S-1 : The old coordinates of the object are x=2 and y =1. Translation coordinate in […]
